public class TableName
extends QueryTreeNode

A TableName represents a qualified name, externally represented as a schema name and an object name separated by a dot. This class is misnamed: it is used to represent the names of other object types in addition to tables.

Method Summary

TableName	cloneMe() Clone this TableName
boolean	equals(java.lang.Object other) Compares two TableNames.
java.lang.String	getFullSQLName() Get the full SQL name of this object, properly quoted and escaped.
java.lang.String	getSchemaName() Get the schema name.
java.lang.String	getTableName() Get the table name (without the schema name).

Method Detail

getTableName

public java.lang.String getTableName()

Get the table name (without the schema name).

Returns:

Table name as a String

hasSchema

public boolean hasSchema()

Return true if this instance was initialized with not null schemaName.

Returns:

true if this instance was initialized with not null schemaName

getSchemaName

public java.lang.String getSchemaName()

Get the schema name.

Returns:

Schema name as a String

getFullSQLName

public java.lang.String getFullSQLName()

Get the full SQL name of this object, properly quoted and escaped.

toString

public java.lang.String toString()

Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing.

Overrides:

toString in class QueryTreeNode

Returns:

This object as a String

cloneMe

public TableName cloneMe()

Clone this TableName

hashCode

public int hashCode()

Returns a hash code for this tableName. This allows us to use TableNames as keys in hash lists.

Overrides:

hashCode in class java.lang.Object

Returns:

hash code for this table name

equals

public boolean equals(java.lang.Object other)

Compares two TableNames. Needed for hashing logic to work.

Overrides:

equals in class java.lang.Object

Parameters:

other - other tableName
